I suppose you mean something similar to Samba's "remote browse sync"

I don't think it is feasible to implement something like this for
mDNS. In contrast to SMB servers mDNS responders never compile
something like a complete browse list, hence there is nothing two
servers could exchange. 

Avahi already does forwarding of mDNS traffic between multiple
interfaces. If latency is good enough you may use that to bridge two

Unicast DNS is definitely preferable when it comes to high latency
links. There's no point in trying to modify mDNS in a way that it is
capable of coping with high latency. There is already unicast DNS which
is perfectly capable to deal with situations like that.
